dwc3: msm: Notify -ETIMEDOUT always in case of floating charger 



Charger driver expects USB driver notify -ETIMEDOUT always on
POWER_SUPPLY_PROP_CURRENT_MAXCURRENT on enumeration failure in case
of floating charger. This is to set ICL to value based on Rp in case of
floating charger. But currently driver is not notifying this, when floating
charger is disconnected and connected back. Due to this, device is charging
only with 100mA instead of current based on Rp value. Fix this by having
proper check and allow to notify in case of floating charger type.
